Activities to Teach Students About Repeating Decimals

Repeating decimals can be a challenging concept for students to grasp, but there are many ways that teachers can make the topic more engaging and interactive. In this article, we will explore several activities to teach students about repeating decimals.

1. Fraction to Decimal Conversion Game

In this game, students will practice converting fractions to decimals. Begin by writing several fractions on the board or a piece of paper. Then, ask the students to convert these fractions to decimals. To make the game more engaging, use a timer to see how quickly the students can complete the task. Finally, have the students identify which of the decimals they produced are repeating decimals.

2. Repeating Decimal Bingo

In this activity, students will play a game of Bingo to identify repeating decimals. Begin by creating Bingo cards that feature repeating decimals. When calling out the numbers, use a mix of repeating decimals and non-repeating decimals. To make the game more challenging, you can also include fractions that convert to repeating decimals. For example, 2/3 is equal to 0.6666….

3. Decimal Place Value Manipulatives

One way to help students understand the concept of repeating decimals is to use manipulatives to represent decimal numbers. Use base 10 blocks or decimal cubes to show students how repeating decimals represent a pattern of numbers that continues infinitely. Encourage students to experiment with different repeating decimals, observing how the pattern changes when the decimals are multiplied or divided by different numbers.

4. Decimal Scavenger Hunt

In this activity, students will search for decimals around the room or school and identify which decimals are repeating decimals. Provide students with a list of decimals to find, or have them come up with their own decimals to search for. Once they have identified a repeating decimal, have them explain how they know it is repeating.

5. Decimal War Card Game

In this card game, students play a version of War with decimal cards. Each player draws a card and announces the decimal they drew. The player with the larger decimal wins the cards and adds them to their pile. To make the game more challenging, include decimals that are repeating and have students identify which ones they are.

Overall, repeating decimals can be a confusing concept for students, but with the right activities, teachers can make the topic more engaging and understandable. Encourage your students to experiment with different decimals and patterns, and don’t be afraid to let them take the lead in their learning. With a little creativity, you can help your students master the concept of repeating decimals and develop a love of math.
